RAG (Retrieval-Augmented Generation)
Definition
Retrieval-Augmented Generation (RAG) is an architecture pattern where an AI system retrieves relevant information from a knowledge base and uses it to inform generated responses, grounding the AI in specific, up-to-date data.
Why it matters
The business case for RAG (Retrieval-Augmented Generation).
RAG dramatically reduces hallucination risk and enables AI to work with proprietary or recent data that the underlying model was not trained on. RAG is foundational for enterprise knowledge workflows.

Cognitive Architecture
A Cognitive Architecture is the structural design of an AI reasoning system, including how it perceives input, accesses memory, plans actions, and learns from feedback. Cognitive architectures are what differentiate sophisticated AI from simple model wrappers.
PRISM
PRISM is SynthesisArc's seven-layer cognitive architecture for enterprise AI. The layers, perception, context, memory, reasoning, planning, action, and learning, combine deterministic and generative AI to deliver consistent, auditable outcomes.
LLM (Large Language Model)
A Large Language Model (LLM) is a foundation model trained on massive text datasets to predict and generate language. GPT, Claude, Gemini, and Llama are all LLMs.
Agentic AI
Agentic AI refers to AI systems that autonomously execute multi-step tasks toward a defined goal, using reasoning, tool use, memory, and self-correction. Agentic AI moves beyond chatbots that respond to systems that act.
Multi-Agent System
A Multi-Agent System is a coordinated set of AI agents working together on a shared goal, sharing context, handing off tasks, and avoiding conflicts. Multi-agent systems are required for any workflow that crosses departmental or functional boundaries.
